Return of the Fruitfly

Well, personally, I’m more bothered with flying ants right now, but quite a few users of macOS/OS X are unsurprisingly concerned right now about the resurgent Fruitfly backdoor/spyware, the subject of an upcoming Black Hat presentation by Synack researcher Patrick Wardle that has attracted a great deal of attention:  Offensive Malware Analysis: Dissecting OSX/Fruitfly via a custom C&C Server. I talked (briefly) about an earlier iteration of the Fruitfly/Quimitchin malware  in January.

Further commentary:

Wardle told Mashable that ‘the entire Fruitfly malware net appears to be shut down at this time.’

Skycure pessimistic about iOS

John Leyden is slightly sceptical of Skycure’s pessimism as regards iOS breaches and vulnerabilities: Martijn Grooten of Virus Bulletin even more so. “Android malware is still far more common. The whole report looks like the authors are desperate to make iOS security sound as bad as possible.”

The article: No one still thinks iOS is invulnerable to malware, right? Well, knock it off – As platform’s popularity continues to rise, so does its allure to miscreants 

Skycure’s report  here,

AV-Test Stats: Spikes in macOS and Android malware

AV-Test offers an interesting aggregation of 2016/2017 malware statistics in its Security Report here.

Particularly relevant to this site:

  • Looking at the growth in malware for specific platforms, AV-Test notes a decrease in numbers for malware attacking Windows users. (Security vendors needn’t worry: there’s still plenty to go round…)
  • On the other hand, the report says of macOS malware that ‘With an increase rate of over 370% compared to the previous year, it is no exaggeration to speak of explosive growth.’ Of Android, it says that ‘the number of new threats … has doubled compared to the previous year.’

MacRansom (& MacSpy)

[Updated 15th June 2017]

(MacSpy isn’t ransomware, but seems to have been developed by the same author, and both are offered as as-a-service malware.)

Zeljka Zorz for HelpNet Security: Two Mac malware-as-a-Service offerings uncovered. According to HelpNet ‘Patric Wardle’s RansomWhere? tool can also stop MacRansomware from doing any damage.’

Rommel Joven and Wayne Chin Yick Low, for Fortinet: MacRansom: Offered as Ransomware as a Service

Sophos: More evidence Mac ransomware exists

Fortinet notes that “Nevertheless, we are still skeptical of the author’s claim to be able to decrypt the hijacked files, even assuming that the victims sent the author an unknown random file…”
